Tally Olivia Adams is a twelve-year-old (just) autistic girl faced with the prospect of a week-long end-of-the-year class trip, which worries her, because there will be "teams" and "activities" and "competition" all of which terrifies her, especially when she finds out she is not bunking with her friend Aleksandra; the other girls on her team are often nasty, especially Skye--and Tally needs all the life-skills she has learned to cope with and expose the bully, and maybe make some friends along the way.
